What is service BD in Assyst Plus?

[SinaW212]

hi, the Assyst Plus on my 2013 S212 is showing it’s due “Service BD” in 30 days! Initially it was showing B7 but it changed to BD a while back. Searched all over internet and there’s no mention of such thing at all! Anyone seen this before?

If you go to page 2 of this section and look for a thread titled "Servicing List .......", all the info you are searching for is in there.
Which is why I suggested that particular thread ought to be made a "sticky"!!!!
